(01. 240-81) l relation sothat the shade may be placed on or removed from the light source withoutdis-assembling it into the component parts, and so as to give readyaccess to the lamp bulb for removal from the socket.

According to the preferred embodiment, this shade is composed of aplurality of more or less conical shaped sheet metal stampings orspinnings mounted on a supporting frame work adapted to receive the lampbulb. The stampin'gs are spaced apart sumciently to permit the escape oflight in an oblique direction and yet sufficiently close to completelyscreen the light source against direct observation.

The accompanying drawing shows, for purposes of illustrating the presentinvention, one

of the many embodiments in which the invention may take form, it beingunderstood-that the.

drawing is illustrative of the invention rather than limiting the sameIn the drawing: Fig. 1 is a side elevational view of a table lampemploying the present shade construction,

the parts being shown in section; I

Fig. 2 is a sectional view on the line 2-2 of Fig. 1; Fig. 3 is afragmentary view of a, shade support taken in the direction of the arrow3 of Fig. 2; and

Fig. 4 is an enlarged detailed view. The base of a lamp is indicated at10. It car- 4 ries a lamp socket 13, andcontrol switch 14 in anysuitable manner. It also carries an upwardly extending tubular member 15adapted to surround the socket 13 and provide a support over which aportion of the shade unit may be 5 telescoped. The shell 15 is providedwith spring prongs 16 adapted to frictionally fit the shade support. Thesocket 13 carries a tubular lamp bulb 17 of slightly smaller outsidediameter than the shell 15. i The shade support just referred to isshown in the form'of a ring or sleeve 20, outwardly flanged as indicatedat 21. It is adapted to slip over the tubular shell 16 and to be broughtdown against a bead 22 carried by the stationary support. l

The lamp 17 is enclosed within the unitary shade, a plurality of sheetmetal stampings 24 beingemployed for this purpose. These stampings maybe all alike and are nested together in spaced relation, as shown in thedrawing.

To accomplish the support of the stampings 24, one may employ a numberof small wire tie rods 25 which extend through holes 26 in the flange 21of the support 20 and through holes 27 in ears 28 in the reflectors 24.Spacers-29 are employed to separate the louvers or reflectors 24. Theupper ends oi the rods 25 extend through an anchor plate 30 and nuts 31and 32 are employed to clamp the parts together. Above the louvers 24,there is a cover member 34, made from a spinning or stamping about likethat employed for the louvers 24, except that it is provided with asmaller aperture 35. This aperture is adapted to re"- ceive a glass knob36 having prongs 3'7 which pass down through notches 38 in the plate 30.

When the lugs 3-7 are turned away from the notches, the stamping 34 issecured against the plate 30 and hence the top of the shade is closedand a convenient knob is provided for pulling the assembled shade offthe lamp.

The direct rays of light from the lamp 1? pass obliquely downward, asindicated by the rays R. The more horizontal rays, as well as theupwardly emitted light from the lamp bulb, are intercepted by the lowersurface of the louvers 24 and reflect- 35 ed downwardly against theupper surface of the next lower louver, where it is directed outwardlyas indicated by the rays R and R".

The shades are constructed to fit standard sizes of lamp bulbs and maybe used with boudoir and table lamps, or with fixtures wherein the lampsare upright. In case the shade is to be used with a pendant lamp bulb,suitable means, such as a bayonet slot connection, will be provided forsupporting it in place.

By making the shade unitary, so that it can be taken off the lamp, it iseasy to effect lamp renewals and to clean the shade and lamp'bulbwhenever necessary.

What is claimed is:

of conical reflectors regularly spaced between the sleeve and anchorplate, clamping rods extending between the sleeveandplate and passingthrough holes in the reflectors, spacer sleeves about the rods andbetween the reflectors, the. reflectors having axial openings so thatthe entire shade may be passed onto the tubular light source, anapertured cover member shaped like the reflectors, and a glass knobpassing through the cover member and anchor plate for securing the covermember in place.

2. A lamp shade for tubular lamp bulbs comprising a plurality of conicalsheet metal reflectors having central apertures large enough to receivethe lamp bulb, and a plurality of small holes adjacent the centralaperture, a sleeve large enough to slip over the lamp bulb and having aflange provided with small holes spaced the same as the holes in thereflectors, an anchor plate provided with similarly spaced small holes,a plurality of rods slightly longer than the lamp bulb and passingthrough the holes, spacers separating the reflectors from one anotherand. from the
